Patented Sept. 15, 1936 UNITED sTA'ras PATENT OFFICE 2,054,327 Y COOKING sTovE on RANGE George L. Jeck, St. Louis, Mo.

Application March 22, 1934, Serial No. 716,764 1 claim. (C1. 126-337) This invention relates to cooking stoves or ranges, and has special reference to improvements in the ovens thereof.

An object of the invention is to provide improved means for supporting and adjusting vertically in the oven of a cooking stove or range a grid upon which the articles or materials to be baked or broiled are mounted.

Another object of the invention is to provide an improved vertically adjustable grid in the oven of a cooking stove or range comprising sliding supports for supporting the grid, so that the grid may be moved outwardly through the open front of the oven irrespective of the height at which the grid is supported in the oven.

Another object of the invention is to provide improved means for operating the grid to diiferent adjusted positions in the oven and the latch device for holding said operating means against accidental displacement.

Other objects of the invention will be apparent from the following description, reference being made to the accompanying drawing, in which- Fig. 1 is an end elevation of an oven of a cooking stove or range having my present invention embodied therein.

Fig. 2 is a front view, the doors of the oven being open.

Fig. 3 is a horizontal sectional view approximately on the line 3 3 of Fig. 1 looking downwardly toward the vertically adjustable grid.

Fig. 4 is a detail View showing the longitudinally movable support for the longitudinally movable grid.

Fig. 5 is an enlarged cross sectional view on the line 5 5 of Fig. 4.

Fig. 6 is a similarly enlarged cross sectional view on the line 6--6 of Fig. 4.

Fig. 7 is an enlarged sectional view on the line 'I-l of Fig. 2 showing the latch device whereby the grids are held against accidental movement.

In the invention shown, the cooking stove or range includes a baking oven I below which is a broiler oven 2. A door 3 is o-perative to open and to close the front opening to the baking oven I and a separately operable door 4 is movable to positions to open and to close the open front of the broiler oven 2. The frame part 5 extends transversely between the front portion of the two ovens immediately below the door 3 and in position to be engaged by the upper portion of the door 4 when the door l is closed. The usual or any preferred fuel burner is within the oven structure to the rear of the frame part 5 below the baking oven I and above the broiler oven 2, in accordance with familiar practice.

A shaft 6 extends transversely across the lower portion 0r below the lower end of the oven I 'through the outer oven wall 'I and through the oven liner walls 8. A crank arm 9 is attached to the outer end of the rod or shaft 6 and is formed with a socket I0 enclosing a spring I I, one end of which seats against the bottom of said socket and the other end of which bears against a collar I2 on a latch rod I3 supported by the arm 9 for sliding movements. A knob or handle I4 is detachably screwedon the outer'end of the latch rod I3 and is engageable and operative to move said latch rod I3 outwardly in a longitudinal direction in opposition to the spring II. A member I 5 is attached to the wall 'I and is provided with an annular series of holes I6 into and out of which the inner end of the rod I3 is movable in order to hold the crank arm 9 and thereby the shaft or rod 6 stationary and prevent rotation thereof. In order to .rotate the rod or shaft 6, it is only Ynecessary to move the latch rod I3 outwardly out of the hole I6 in which it is engaged. Then the crank arm 9 may be turned to rotate the rod or shaft 6 in the direction desired and the latch rod I3 engaged in the corresponding hole I6 to prevent further or accidental turning of said rod or shaft 6.

A pair of pinions I 'I are attached to the rod or shaft 6 adjacent to the inner surfaces of the oven liner walls 8 and are in permanent mesh with racks I8 formed on the inner sides of vertically movable frames I9.

A pair of channel bars are attached to each frame I9 by fasteners 2|, the channels of said bars being toward each other. The rear ends of said bars 20 have laterally bent portions 22 engaging the rear edges of vertical angle bars 23, constituting guides and cooperating with the frames I9. The front ends of the bars 20 have laterally bent portions 24 engaging the front edges of angle bars 25. The fasteners 2| for each bar 26 are spaced substantially forwardly and rearwardly and are at opposite sides of the openings in the frames I9 and near the margins of said frames. Thus, the frames I9 are supported and guided vertically and are prevented from tilting forwardly or rearwardly to any substantial extent.

An angle bar 26 is mounted for longitudinal sliding movements forwardly and rearwardly in each angle bar 20 and is held from displacement therefrom by a projection 21 from the angle bar 26 engaging in a slot 28 in the angle bar 20. Thus, the angle bars 26 are held on the angle bars 20 and extent of movement thereof is limited by the length of the slots 28.

A grid frame 29 hask its side members 30 mounted in and supported by the angle bars 26. Said grid frame is movable longitudinally along the angle bars 26, extent of outward movement of said grid frame being limited by lugs 3| projecting from the angle bars 26 in position to be engaged by the rear members 32 of the grid frame. Y

As shown, there are twoof these grid frames supported by the frames I9 within the oven I and said grid frames are spaced vertically one above the other. They are of duplicate construction and the foregoing description sufficies for both. Y

A rod or shaft 33 is rotatively supported by the walls 'I and 8 below the broiler oven 2 and Y is equipped on its outer end with an operating crank 34 having a spring actuated latch member and handle 35, similar to the spring actuated latch member and handle l3--I4 in connection with the crank arm 9 and operating to engage in holes 36 in a member 3l, similar to theA manner in which the latch member I3 engages in the holes I6 in the member I5. Pinions 38, attached to the rod `or shaft 33, mesh with racks 39Von the inner sides of frames 40. Channel Vbars 4I, similar to the channel bars 20, are attached to the frame 40 and engage the guides 23 and 25 in like manner. Channel bars 42, similar to the channel bars 26, are mounted for sliding movements forwardly and rearwardly in the channel bars 4I and are guided Y and limited in their movements in the same of most any construction now in general use. The device may be constructed and mounted in the ovens without diioulty and at low cost. By vertical adjustment of the frames in the baking oven and by vertical adjustment of the support 43 in the broiler oven, best results and effects may be obtained.L

The construction and arrangement of the parts comprising the invention may be varied within the scope of equivalent limits without departure from the nature and principle of the invention.

I claim: V

In an oven the combination of a top, a bottom having slots therethrough near its side edges,

Y a rear wall, a front Wall provided with a door,

side walls extending below the bottom and having openings in the extensions, a shaft located in the openings, gear wheels xed to the shaft,l one near each end, an elliptical frame extending through each slot in the bottom and surroundingboth the shaft and a gear wheel there- Vthe Velliptical frame, a slidable shelf mounted in the guide bars, lugs on the slidable shelf to contact a portion of the oven and prevent the Vslidable shelf from disengaging the guide bars,

a slide telescoping with the slidable shelf, means to prevent the telescoping slide from disengaging the shelf, means for rotating the shaft to raise and lower the elliptical frames simultaneously whereby articles carried on the shelf and the slide may be located in any desired Zone in the oven and means for holding the article carrying elements rigidly in the selected Zone.
